Book Factory — website and iPhone app. Last updated 23 August 2026.
Book Factory is operated by ZPresso LLC. By using the website or the iPhone app you agree to these terms.
One account, one person. Keep your password to yourself — anything done with your account is treated as done by you. Tell us if you think someone else has got into it.
Books made on our AI spend credits. Before a book starts you are quoted a fixed price; that amount is charged when the book starts, and refunded in full automatically if the book fails. Credits are not cash, have no value outside Book Factory, and are not exchangeable. Purchases are made on the Book Factory website, not inside the app.
The books you make are yours to use, sell and publish. You are responsible for what you put in and what you do with what comes out — including checking anything the book states as fact before you rely on it or publish it.
We work to keep Book Factory running and to fix what breaks, but the service is provided as-is. AI writing is not perfect: it can be wrong, dull, or off-brief, which is why every book can be revised. We are not liable for what you publish or for indirect losses. Where we are liable, it is limited to what you paid us in the previous twelve months.
You can stop using Book Factory whenever you like and ask us to delete your account. We may suspend an account that breaks these terms.
